उत्तर
Cations are present in the interstitial sites in frenkel defect.
Explanation:
| Defect | Definition | Type of solid |
Effect of defect on density of substance |
Structure of crystal (with defect) |
| Frenkel Defect or dis- location defect |
A crystal is said to have Frenkel defect if cation is missing from the normal lattice position and is occupying interstitial site. |
